Description
Technical field
The present invention relates to REID, infrared sensor monitoring, radio transceiver technology, IMAQ and alarm technique.Relate in particular to a kind of well site, oil field monitoring and alarming system and method based on wireless radio-frequency.
Background technology
Along with fast development of information technology and the informationalized propelling of Chinese national economy, round Realization information computerization and information resources are shared and are necessitated in existing environment.The informatization in oil field also is very urgent.The producing well in oil field, petroleum pipeline and storage tank major part in the open air, continuously normally the safety storing and the economic benefit of enterprises of continuous transmission, the storage tank of operation, petroleum pipeline are closely bound up for oil pumper.Real-time monitoring to the duty of equipment such as producing well is important and difficult content of production operation unit always.For a long time; Indispensable during floor manager or maintenance mans' regular inspection; But continuous quickening along with oil field modern management process; Press for a kind of round-the-clock, 24 hours unmanneds and get monitor mode, can not caused unnecessary or even tremendous loss by the sabotaging of lawless person to guarantee producing well equipment.At present for ensureing that the monitoring method that the oil pumper equipment safety operation is taked mainly contains: utilize single on-the-spot induction type alarm or camera head, 24 hours recording monitors are carried out in the working site.This monitoring mode video recording retain costs is higher, and the possibility of produce wrong report, failing to report is very big, and monitor terminal needs staff's whole day to wait for.In case on-the-spot induction type alarm or apparatus for making a video recording are impaired or destroy its power-supply unit, whole monitoring system can't effectively be reported to the police.Therefore the oil field equipment safety monitoring should be adopted the three-dimensional type wireless supervisory system of ground location and air surveillance, and this monitoring method has practicality and high efficiency, and is with low cost, advantages such as simple operations.
Summary of the invention
The present invention is directed to above-mentioned prior art problems and weak point, proposed a kind of well site, oil field monitoring and alarming system based on wireless radio-frequency.The method for supervising that this system adopts the multiple spot ground location to combine with air surveillance.The method is carried out the monitoring of comprehensive multi-angle targetedly for the complicated characteristics of open-air oil well perform region terrain environment.Use infrared detector in the oil well perform region.Signal Processing and coding techniques through microprocessor MSP430F149; The warning accuracy rate of native system is improved greatly; The effectively interference of toys such as filtering fitful wind, flying bird, mouse, cat; And only longer to the duration, the personnel activity that signal reaches the setting degree effectively reports to the police, and the warning accuracy rate of supervisory system can reach more than 90%; Owing to adopt the single-chip microcomputer digital coding, improve code length, thereby improved the antijamming capability of data transmission, the reliability of system is effectively improved; In order to reduce the possibility of wrong report, when having personnel or animal to be strayed into the workspace, alarm sends red light and apery sound please it leave.Microcontroller is also through radio receiving transmitting module control camera device in addition.In case have the crime molecule to get at which defence area on-the-spot crime from, the infrared induction module is sent trace command to camera head immediately.Coloured picture is captured in this zone, sent video simultaneously to administrative center, this road camera carries out video record simultaneously, and video file storage is in the SD card that product carries, and video time can freely be set according to actual conditions, and can long-rangely control.Just more can directly get on the popular alarm platform that is dealt into glibly of live video in the terminal; The platform staff can long-rangely see that the ruffian propagandas directed to communicate; Intimidate it and leave, abandon the thought of committing a crime, also can platform video or SD card video and coloured image be offered law enforcement agency afterwards and handle.In addition, native system has also designed at vitals such as oil pumpers and has carried out independent protection.For example: oily motor-pumped well mouth, consumer unit, indicator, tensimeter etc.At its outside accurate pyroelectric sensor and radio receiving transmitting module installed, utilize the working power power supply of parts own, the position is easy for installation, is difficult for being destroyed.Played the effect of second protection for the oil pumper operate as normal.At last, in order to strengthen and the modular working system, getting into place, oil well workspace installation authentication card machine.This part comprises radio frequency identification module, wireless transmitter module.Staff's entering of need swiping the card.At this moment, the wireless radio frequency modules in the punched-card machine can send to the terminal to cardholder information through common control equipment, and the terminal can automatic recording-related information, closes corresponding alarm device after examining identity.This process can be shot with video-corder working situation in Long-distance Control when needed.This new device utilizes advanced sensor detector and video equipment, intercoms mutually through wireless radio frequency modules, has set up safety, and is efficient, solid protection system.Special call-by mechanism is adopted at wireless monitor and video recording terminal, and the most of the time is in the low-power consumption standby state, only when receiving remote command, converts duty automatically to.Improve safety monitoring efficient, and solved the low-power consumption problem of wireless monitor.
The technical scheme that the present invention adopted is:
A kind of well site, oil field monitoring and alarming system based on wireless radio-frequency comprises: the on-the-spot well head monitoring alarm device in oil field, common control equipment and tension management software.
Said well site, oil field monitoring and alarming system based on wireless radio-frequency is shown in figure one.
Said a kind of well site, oil field monitoring and alarming system based on wireless radio-frequency is divided into field operations district monitor terminal and oil pumper vitals monitor terminal.Field operations district monitor terminal is made up of through the infrared detection sensor unit of microprocessor controls quadruplet, can cover monitoring oil field shaft mouth perform region.Oil pumper vitals monitor terminal can be monitored near the equipment object by through the forming near the formula sensor of microprocessor controls.Monitor terminal is formed wireless star-network as shown in Figure 1 according to certain rule and common control equipment after installation, keep a convergent state.Special call-by mechanism is adopted at the terminal, and the video record device only after receiving remote command, becomes duty from the low-power consumption standby state exchange automatically, and carries out data acquisition according to appointed task.
